Review Summary

What makes Tom Cruise run — run harder and run faster, leaping from one building and dangling off another, the world’s tallest — as he does to exhausting, unnerving effect in “Mission: Impossible — Ghost Protocol,” his latest exercise in extreme performance? The fourth in the franchise, this “Mission” has a solid cast, including a notable new co-star in Jeremy Renner; a new director, Brad Bird; and a story that’s as nonsensical as any in the series. Mostly, though, it has Mr. Cruise hurtling through the movie as if his life depended on it, which, to judge by the hard line of his jaw, his punishingly fit body and the will etched into his every movement, may be what’s at stake. — Manohla Dargis
